Kylie Jenner seemingly has a perfect life, but it doesn't mean that she feels completely happy with herself. The Kylie Lip Kit founder is said to be feeling insecure about her looks although she always appears confident.

According to OK!, Kylie "still feels like the ugly runt of the litter" and it makes her incredibly fragile. "Kylie's had to go through a lot - her folks' divorce and dad's transition, not to mention a cheating sponging ex-boyfriend," an insider tells the website. "She's been hoping 'faking it until she makes it' will work, but she's incredibly fragile and fast becoming totally out of touch from everyone."

The insider explains that the 19-year-old makeup mogul is very sensitive. "She's always off in her own little world and starts crying at the slightest hint of an argument," the insider shares. "Having to cope with almost overnight fame and adulation when deep down she feels like a total fraud is completely messing with her head."

Her condition reportedly makes her father, Caitlyn Jenner, really worried as she believes her daughter may experience a meltdown soon. "Her dad wants her in therapy - there really are worries she's going to crash and burn any day now," the insider says.

Although Kylie may feel insecure about her looks, she is obviously confident with her body as she often shows off her figure. The "Keeping Up with the Kardashians" star wasn't shy to ditch her bra during a night out with her pals two weeks ago. Kylie also didn't hesitate to go topless for a photoshoot.
